Abstract: A method of simulating the activity of the human nervous system includes providing a networked server for access by a user of a general purpose computer, with a database having predetermined data on human nervous system activity being in communication with the networked server. User information is input into the general purpose computer which is correlated with data in the networked database to determine what part of the human nervous system is impacted by the user information input. The general purpose computer displays a simulated image of a portion of the human nervous system and animates the impacted part of the human nervous system determined in the correlation.

Abstract: A centralized, online clinical study system configured to coordinate aspects of a clinical study can include a training module configured to evaluate whether users have completed training for selected workflows for the clinical study that are available from the clinical study system, and to provide training to registered users for the selected workflows. The system also can include a financial engine configured to determine when a participating site meets or exceeds a milestone of the clinical study and to initiate a payment to the participating site. Further, the system can include a module configured to receive and verify clinical research data and to designate the verified clinical research data as official source data for the clinical study.

Abstract: A valve for controlling the flow of fluids through a cannula or catheter made up of a single block piece in the shape of a backward "7" having a head and a stem. As the stem is raised in relation to the hub of the cannula or catheter, the head blocks any flow through the cannula or catheter; as the stem is lowered, the head retracts allowing the flow to continue.

Abstract: An automated ledger account maintenance system provides up-to-the-minute balances in all ledger accounts whenever data relating to a completed transaction is entered. The system is implemented on a general purpose computer and includes a predefined data file structure including ledger account data files corresponding to the ledger accounts and transaction record data files corresponding to transaction journals. Compliance with user definable accounting procedures is ensured through the use of an accounting control table that contains symbolic codes used by the recordkeeping procedures to authorize and control the creation and updating of the ledger account and transaction record data files. Cross-referencing and indexing of ledger account records, transaction records, and the second control records is provided to ensure a high degree of resistance to unauthorized alteration of the data files and to provide for traceability of all entries and postings.

Abstract: A surgical or medical implement including a proximity detector to indicate the distance from an internal organ or member such as an artery. In one form the invention is applied to a surgical scalpel (12) with an audio transducer in contact with the blade (11) and connected to an electrical circuit (18) for providing a warning signal. In another form the invention is applied to a hypodermic syringe (50) with a transducer (60) in contact with the needle (56) and connected through circuitry (62) with a warning lamp or buzzer (63,64).
